Optimising the electrochemical reduction of CO₂ to oxalic acid in propylene carbonate

Abstract

Carbon dioxide (captured from the atmosphere or obtained by other routes) constitutes a useful and widely-available building block for producing numerous valuable chemicals and fuels. Electrochemical methods for carbon dioxide...

Evaluating the native oxide of titanium as an electrocatalyst for oxalic acid reduction

“…Oxalic acid holds considerable promise as a sustainable chemical feedstock because it can be directly synthesised from carbon dioxide gas with high selectivity through electrochemical or catalytic methods. 1,2 Oxalic acid is used in various industrial processes as a precursor to other chemicals, including glyoxylic and glycolic acids. During the electrochemical reduction of oxalic acid, Amin et al 3 reported that oxalic acid is first reduced by two electrons to give glyoxylic acid.…”
